The combinatorics of $\tau$-covers
by Mildenberger and Shelah and Tsaban. [MShT:858]
Topology and its Applications, 2007
We compute the critical cardinalities for some topological
properties involving tau-covers. A surprising structure
counterpart of one of the computations is that, using Scheepers'
If X^2 satisfies S_fin (Gamma,T), then X satisfies
Hurewicz' property U_fin (Gamma, Gamma) .
Some results on the additivity of these properties and special
elements are also provided.
